Abstract
The present invention relates to a plasma display with a laminar attachment structure which can be used for increasing the attaching area and the compactness between a plasma display panel and a heat radiation metal plate. When the heat radiation metal plate penetrates through the laminar attachment structure to be combined with the plasma display panel, air in a closed loop is extracted by a heat conducting pad or double side adhesives which have a plurality of small sheets and a closed loop which holds the heat conducting pad or the double side adhesives with the small sheets in a vacuum air extracting way. Therefore, air bubbles between the plasma display panel and the heat radiation metal plate can be reduced, and the attaching area and the compactness are increased.
Description
Technical field
The present invention is about a kind of plasma display, especially refer to a kind ofly has the plasma display that can increase the stratiform of applying degree between Plasmia indicating panel and heating panel attaching structure (laminar attachment structure), and make heating panel be attached to method on the Plasmia indicating panel.
Background technology
Because the variation of information equipment trend, flat-panel screens (Flat Panel Display, FPD) demand is urgent day by day, and move towards under the trend of compact and power saving in current world market, (Cathode Ray Tube CRT) is replaced by flat-panel screens cathode ray tube gradually.The technology that is applied in FPD at present mainly contains following several: plasma display (Plasma Display Panel, PDP), LCD (Liquid Crystal Display, LCD), electroluminescent display (Electroluminescent Display), light-emitting diode (Light Emitting Diode), vacuum fluorescent display (Vacuum Fluorescent Display, VFD), field-emitter display (FieldEmission Display, FED) and electrochromics display (Electrochromic Display) etc.
Plasma display (PDP) is to make the gas in discharge space (discharge cells) produce discharge (electricity slurry effect just) and luminous plane Display Technique, its structure comprises a plasma display floater 10, a slice heat conductive pad (thermal pad) or double faced adhesive tape (adhesive doubletape) 2, one metallic plate (metal plate) 3 and a plurality of drive circuit (not shown) as shown in Figure 1.Plasmia indicating panel 10 is by a header board 11 and back plate 12 be combined intos, and by sheet heat conductive pad or double faced adhesive tape 2, metallic plate 3 is sticked on the rear side of back plate 12, so the elevated temperature heat that Plasmia indicating panel 10 is produced (high-temperature heat) can conduct to metallic plate 3 by sheet heat conductive pad or double faced adhesive tape 2 and dissipate, the rear side that described drive circuit then is installed in metallic plate 3 constitutes a plasma display apparatus module.
Because plasma display often is applied on the screen panel of large scale (large-dimension), and panel is through processing the slightly deformed that is caused, make sheet heat conductive pad or the double faced adhesive tape 2 actual areas that are fitted on Plasmia indicating panel 10 and the metallic plate 3 be used for linking Plasmia indicating panel 10 and metallic plate 3 have only 40%-50%, and the area of other 60%-50% all contain bubble (bubble).Thus, the degree of sticking between Plasmia indicating panel 10 and the metallic plate 3 reduces, and heat conduction is also because of contact area reduces variation, and not only waste material also causes cost to increase.
Summary of the invention
